Question

When sodium comes into contact with water, an exothermic reaction occurs. Which of the following is an example of an exothermic reaction?

Answer 1

Step-by-step explanation:

An exothermic reaction gives off heat energy. Condensation is the process by which water vapor turns into liquid water. This typically occurs when water vapor molecules come into contact with cooler molecules..

This causes the water vapor molecules to lose some energy as heat.
